Definitions

• the invention relates to a contactlessly operated sanitary fitting with a water outlet connected to a water pipe, a mixing valve inserted into the latter and a shut-off valve connected upstream thereof and controllable by an proximity sensitive sensor Sensor can be actuated, a turbine inserted into the water pipe and a generator assigned to it, preferably connected to an energy store, being provided to supply the control device with electrical energy.
• a sanitary fitting of this type is known from DE-Cl-39 05 759.
• the water line is designed as an annular channel into which the blades protrude into the turbine.
• the generator, the ⁇ / shaft carrying the blades of the turbine and a transmission gear are arranged in a separate housing.
• the object of the invention is therefore to design a contactlessly operated sanitary fitting of the type mentioned in such a way that the electrical energy emitted by the generator can be fed directly to the control unit or the energy store without problems and almost without loss, and that no special seals of the Generator or other components.
• the aim is to ensure that the generator can operate at high speed without the need for a transmission gearbox with losses, so that the flow energy of the water is used efficiently and, consequently, it is highly efficient.
• the manufacturing effort required for this should be kept low, and the parts to be inserted into the water pipe should also be simple in terms of their construction
• this is achieved with a sanitary fitting of the aforementioned type in that the impeller of the turbine is mounted so as to be drivable directly in the water duct of the water pipe about an axis extending in the direction of flow and in the outer region with a plurality of permanent magnets arranged uniformly distributed over the circumference is equipped, and that in the wall of the water pipe or on top of it at the level of the permanent magnets two or more magnetic coils are used, which in cooperation with the permanent magnets arranged in the impeller of the turbine form the generator.
• the water pipe with a first and a second flow-through intermediate wall, between which the impeller of the turbine is arranged and which is rotatably supported in the intermediate walls by means of centering tips and centering holes
• the first intermediate wall connected upstream of the turbine impeller should have one or more nozzle openings incorporated into the outer region thereof and preferably arranged inclined in the direction of flow, and the impeller with the diameter region of the nozzle openings the first partition preferably arranged perpendicular to these inclined guide vanes, the number of guide vanes of the impeller should correspond to the number of nozzle openings machined into the first partition. It is also indicated to equip the turbine impeller with an axially protruding shoulder, which engages in a freeing of the water pipe and in which the permanent magnets of the generator, which is preferably designed as a synchronous generator, are inserted.
• the impeller of the turbine can be provided with guide vanes which are arranged radially inside the permanent magnets and can be acted upon by the flowing medium.
• the two intermediate walls on the outer sides and / or the impeller of the turbine on the side facing away from the first intermediate wall can have cone-shaped, aerodynamically shaped extension pieces.
• the two intermediate walls and the impeller of the turbine inserted between them can expediently be arranged in a conical shape formed in the water pipe.
• the energy store can be formed by a capacitor
• a sanitary fitting is designed according to the invention, there is not only a compact structural unit which can be used almost anywhere and also retrospectively and which enables trouble-free operation without connection to a power supply system, but the electrical energy can also be easily and without major losses from it Generator are transferred to the control unit or the energy store. Slip contacts are not necessary for this, nor are there any electrical cables to be arranged in the water line, the coils inserted into them are rather stationary and can be electrically connected to the control unit or the energy store without any problems. And there the shovels of the Turbine impeller when water is withdrawn from the nozzle openings and thus flows at high speed, high speeds can also be achieved. A sufficient amount of energy is therefore always available to operate the sanitary fitting. In spite of the low construction costs, a high degree of utilization of the energy contained in the water is provided and trouble-free and maintenance-free operation is ensured over a long period of time without batteries having to be replaced and disposed of.
• FIG. 1 shows the sanitary fitting in a schematic representation
• FIG. 2 shows the water line provided with the turbine and the generator in a longitudinal section
• FIG. 6 shows a different design of the turbine and the generator in a representation according to FIG. 2.
• the sanitary fitting 1 shown in FIG. 1 has a mixing valve 6 and a shut-off valve 8 connected downstream thereof, which can be controlled by means of a sensor 10.
• This consists of a cold water line 2 and a hot water line 3 via branch lines 4 and 5 to the mixing valve 6 supplied water is mixed in this in accordance with the water distribution set and can flow out of a water outlet 9, to which the mixed water is supplied via a water pipe 7, as soon as the shut-off valve 8 is opened as a function of a pulse emitted by the sensor 10.
• a control unit 11 which is connected to the sensor 10 via a signal line 12 and a further signal line 13 to the shut-off valve 8, is used to excite the shut-off valve 8 equipped with an armature winding as a function of the pulses from the sensor 10.
• a control unit 11 is designed as a rechargeable battery or as a capacitor for supplying it with electrical energy and for supplying the armature winding of the shut-off valve 8 via a line 15
• Energy storage 14 connected. Operation without the energy store 14 is also possible.
• the water supply to the water outlet 9 is thus controlled by means of the control device 11, and water mixed with cold and warm water as soon as the control device 11 is activated by the sensor 10 is supplied to the latter according to the setting of the mixing valve 6.
• a generator 31 is assigned to it, which is connected to the energy store 14 via a power line 34.
• the generator 31 is in drive connection with a turbine 21, which can be driven to rotate about an axis A extending in the flow direction by the water flowing in the water line 7.
• the turbine and the generator 31 -21 are, as can be seen in particular from Figure 2, in a tube socket designed as a 'piece fitted 16 which for this purpose has a conical extension 18 and by means of Thread 17 is easy to insert in a line.
• the pipe section 16 is equipped with a first intermediate wall 23 and a second intermediate wall 24, between which the impeller 22 is mounted between tips.
• an insert 41 is inserted into the impeller 22, which is provided on one side with a centering tip 42 and on the other side with a centering bore 43 into which a centering tip attached to the first intermediate wall 23 is provided 44 engages.
• the centering tip 42 of the insert 41 engages in a centering bore 46 of an insert 45 which is inserted into the second intermediate wall 24, which is provided with flow channels 24 ′′ and can therefore be easily flowed through.
• nozzle openings 25 are machined into the first intermediate wall 23 in the outer diameter range, and the impeller 22 of the turbine 21 is equipped with these associated guide vanes 26, which thus take off at high speed when water is withdrawn are discharged from the nozzle openings 25, so that the impeller 22 of the turbine 21 rotates at high speed.
• the turbine 21 ' is arranged radially inside the generator 31'.
• the impeller 22 'of the turbine 21' equipped with guide blades 26 ' is rotatably held between two centering tips 42' and 44 'attached to the intermediate walls 23' and 24 'and carries the permanent magnets 32' of the generator 31 'on the outer circumference. which, when the impeller 22 'rotates, interact with the magnetic coils 33' inserted into the wall 16 'of the pipe section 16, so that in turn electrical power is induced in them, which is transmitted via the power line 34 to the energy store 14 or directly can be fed to the control unit 11.
